Tolerance values for the concentration
If the
SynchroFeed
functionality (optional) of the feeder is used, then the animals all drink at
the same time in the boxes, which are supplied in parallel, from the portion mixed in the mixer
beaker of the feeder.
If two animals are drinking in parallel and have been assigned different concentration values,
the tolerance value for concentration decides whether both animals can drink at the same time
or not.
For example:
A feed with a concentration of 120 g/ltr is prepared for one animal. For a second
animal a concentration of 110 g/ltr was agreed. At the default setting of ±20 g/ltr for the concen-
tration tolerance value, these two animals can share the feed: The difference between the con-
centration value of the mixed feed (120 g/ltr) and concentration value for the animal’s feed plan
(110 g/ltr) is less than the agreed tolerance value (±20 g/ltr).
If on the other hand 0 g/ltr was agreed as the tolerance value, according to preference mode
the feed for the latter animal would not be dispensed until after the animal consuming first had
consumed his entire portion.
You can define the tolerance as follows:
1. Navigate via
> Device data
to the
Portion
sub-menu.
2. In the
Tol. Conc.
menu, set the desired value and confirm with

Mixer draining
Feed left over in the mixer must be pumped out. This is done either via the mixer drain valve or
the teat. Alternatively, you can choose not to pump out residual amounts at all.
NOTICE!
Leftover feed in the mixer can lead to an increased risk of infection when outdoor tem-
peratures are high (summer). When outdoor temperatures are low (winter), leftover feed
in the mixer becomes so cold that calves will no longer drink it.
This can lead to malnutrition. Malnutrition can cause impaired growth and development, in-
creased susceptibility to illness or even death of the calves.
Leftover feed in the mixer beaker provides a perfect breeding ground for germs. You specify the
amount of time after which this leftover feed is discarded in order to ensure optimal feed hy-
giene. Mixer draining may also be followed by a drainage procedure (see the
Cleaning
chapter
in the operator's manual for the automatic feeder).
Mixer draining via mixer drain valve
The best and simplest solution is to evacuate the contents of the mixer via the mixer drain valve.
You specify whether a mixer drain valve is fitted during setup (see 5.5.1 "Mixer drain" - 64).
